I have only had to pull my firearm for self defense one time, in 2005. While I was ready to fire, the person upon whom it was pulled started crying and ran away. The story goes as follows:
Me and two friends were at his house when we get a call(around 10:00 pm.) from another friend who got stuck in the mud while 4 wheeling. So friend A goes around to the back of his house to get his truck, while me and friend B go to the front of his house, walk up the stairs to the road, and wait to get picked up by friend A. While waiting on friend A to bring his truck around, friend B and I notice someone standing near a car down the road. We saw him looking around as he got closer to the car, but from where he was he couldn't see us. We then saw him bend over, slash the tires on the car, look around again, and proceed to walk in our direction. When he got almost right in front of us he saw us, and looked over and said "what's up fellas?" I noticed from the first time I saw him that he was carrying something, which up until he got close I thought was a tire iron. It turned out to be a hunting type knife, which he was still carrying open in his hand until. After he first talked to us with the "what's up fellas", friend B asked him if he had just slashed the tires on that car. He then stopped walking, turned and said "no I was just checking my watch." When he stopped walking I had already placed my hand on my gun. Friend B then told him that it sure looked and sounded like he just let the air of that cars tires. The guy then took one step towards us when I pulled my G19 and pointed it at him and told him not to take one more step towards us. He just started balling crying and ran off down the road. I was shaking horribly after it happen, as that was the first and only time that I have ever felt threatened enough by someone to pull a weapon on them.
